MACHINE FOR CONNECTING WIRES.

SPECIFICATION forming part of Letters Patent No. 352,853, dated November16, 1886.

'- Application filed September 4, 1886. Serial No. 212,652. (No model.)

I at whom it may concern.-

Be it known that I, ALONZO L. BRUSH, of the city of Decatur, county ofMacon, and State of Illinois, have invented a certain new and usefulMachine for Connecting Wires, of which the following is a specification.

My invention consists in certain details of construction andcombinations of parts, as hereinafter set forth and claimed, wherebywires to may be joined together with a double reverse coil, asspecifiedherein.

In the drawings accompanying and forming a part of this specification,Figure 1 is a plan of my machine. Fig. 2 is a side view of a portion ofthe same. Fig. 3 is a side view of a clamping-die with itssecuring-screw. Fig. 4 is a face viewof the twister-wheel. Fig. 5 is aface view of the drive-pinion. Fig. 6. is a face view of thetwister-die, and Fig. 7 represents the coil-connection my machine isdesigned to make.

a represents an ordinary brace-crank, provided with handle I). y

cis a tubular bearing for the braceshaft, composed of two parts suitablysecured together.

' 0 is a bracket-bearing, of suitable size and conformation,to hold thetwister-wheel at right angles with the pinion 0n the brace-shaft.

d is a drive-pinion rigid on the brace-shaft,

0 and provided with an enlarged tooth, d. e is the twister gear-wheel,cleft ate and pro-- vided with enlarged space 6 at a point in thegearing directly opposite cleft e.

f is a casing for the .lower portion of the 3 5 twister-wheel, in whichcasing is a bearing for transverse shaft Z. 9 represents upperclamping-arms, and 9' represents lower clamping-arms, said arms 9 and 9being pivoted together in pairs and pro- 40 vided with jaws h. v

i are lateral guides for the clamping-dies in jaws h, which dies areconnected in pairs by means of a screw, 15. k are extensions of thejaws, which form bearings for transverse shaft Z. 5 m are springs onshaft Z, that hold the bearings k in the positions show-n, butpermitthem to more nearly approach each other when lateral pressure isapplied.

Pairs of arms 9 and g are each provided with a handle, as indicated byn,,by means of which their approach and the approach of the jaws may beregulated.

l 0 represents the twister-die, and oin Fig. 4 indicates by dotted linesa screw used to secure the die in position in the twister-wheel.

1) represents a clamping die, with one of which each jaw is provided.

q represents screws for holding the dies 'in the jaws by having itsthreaded end engage a threaded opening in said die, as seen in Fig. 3.0' and s in Fig. 7 represent two wires joined together by the operationof my machine.

In Fig. 2 the jaws are shown as partly opened and the'crank of the braceis omitted.

Dies of different capacity may be placed in the twister-wheel andclampingjaws, respectively, thus enabling wires of various diameters tobe joined together.

In operation the wires to be joined arelapped to an extent sufficient tobe caught by both sets of jaws, the handles a are grasped by the lefthand of the operator, and the jaws opened Sl ficiently to permit thefree passage of the wires, which are put in the twister-wheel andclamping-jaws by the use of the right hand. The jaws are next firmlycompressed on the wires by drawing the arms together, the head of thebrace is placed against the person of the operator, and the crank turnedby the righthand until a requisite number of coils have been formed bythe twister-die, when the jaws are opened and the connected wiresremoved. The large tooth'd of pinion d meshes always with the cleft inthe twister-wheel and the enlarged space directly opposite said cleft,thus produc- 8 5 ing a regular rotation and a perfect operation.

The handle of the brace should hang at its l lowest possible positionwhen the cleft of the twister-wheel is in incidence with theclamping-jaws, as by this means all tendency of the said cleft and jawsto become disarranged while the operator is using his right hand toplace the wires in the machine will be avoided. As the wire is twisted,it is to some extent shortened, and the springs m permit the pairs ofjaws to approach each other in conformity to the shortening of thewires.

My machine, as specified, may be used for baling hay, 850., for makingwire fence, for connecting telephone and telegraph wires, and in allcases where it is desired to connectone wire with another in a permanentmanner.

l. A machine for connecting wires, consisting in the combination of acleft gear-wheel having an enlarged space in its gearing directlyopposite the cleft, a drive-pinion one-half the diameter of thecleft-wheel in mesh therewith, and provided with an enlarged tooth inposition to mesh with the cleft and with the enlarged space of thetwister-wheel, a shaft for the pinion, means for rotating the shaft, anda pairof clamping-jaws on each side of the cleftwheel on a line with thecleft thereof, as and for the purpose set forth.

2. A machine for connecting wires, consisting in the combination ofacleft gear-wheel, a l

pair of clamping jaws on each side of the twister-wheel on a line withthe cleft thereof, having a limited degree or" motion toward the wheel,springs to hold the jaws normally at their greatest distance from thewheel, a drivepinion in mesh with the twister-wheel, ashaft for thepinion, and means for rotating the shaft, as and for the purpose setforth.

3. A machine for connecting wires, consisting in the combination ofbrace a b, pinion d,

cleft-wheel e, bearings c 0, clamping-jaws h, having arms 9 g, handlesn, rod Z, springs m, and bearings k, as and" for the p11 rpose setforth.
